Chloe Ko

Seoul-born, New York-based designer Chloe Ko began her career within a French luxury fashion group before transitioning into design through her studies at FIT.

Her journey into fine jewelry is rooted in Manhattan’s Diamond District, where she continues to work closely with master artisans. She finds clarity by reducing rather than adding, refining each piece to its essential form.

The result is KOER. Fine jewelry where emotion is held in form.

Sustainability

At KOER, sustainability is not an addition.
We make only what is needed.

Every piece is made to order.
No excess. No unnecessary inventory.

Materials are sourced thoughtfully.
Production remains small and deliberate.

Like the pieces themselves,
our practices are continually reconsidered.

Not more. Not less.

The Three Diamonds

Three diamonds appear throughout KOER.
Not as a symbol, but as a signature.
A small mark of consideration, repeated throughout KOER.

Craftsmanship

Within Manhattan’s Diamond District,
quality is not a given.

It is a choice.

KOER works with the most skilled hands.

Chosen for precision,
consistency,
and care.

Every piece carries the KOER name.

That is the standard.
